And some astronautics expert believed jordan alpha 1 for sale    that this satellite falls down the time possibly is on the 22nd of the month or on 23rd, crashes the place unknown.   Not big components crash the Earth   This abandonment satellite named “Roentgen”, it is reported that it after entering the earth's atmosphere, will produce rubs and decomposes, 1 ton about spare part will burn the danger, but will still have 1.4 ton about wreckage to be able to crash the ground. cheap jordan alpha trunner At present its flight speed is 28,000 kilometers.   German Space agency official fertile Naer said that in the wreckage including the big spare part, only will not have some tiny things to crash, for instance mirror surface, glass and ceramic part and so on.   Regarding wreckage whether to hit the humanity, fertile Naer said that this possibility will be small, only then 1/2000, moreover, even if is hit by the fragment the words, are been also miniscule the severely wounded possibility.
